I’m going to give a different spin of an answer.
I will harmonize with @deep_333 that this is not a good loudspeaker by today’s standards. There are many modern speakers at this price point that will sound better. It is a product of the time when time alignment using a sloped cabinet was a fad. Designers had to make serious design compromises to make these designs work. The measurements suggest this speaker is room and placement sensitive.
Reasons to consider it? (Provided the drivers are in good shape)
1. You want to own a piece of audio history. It’s a definite conversation piece.
2. You primarily listen to rock or metal, or otherwise like an exaggerated bass punch. (The bump in bass output centered around 100 Hz is a known to be perceived as bass punch.)
